They were arrested on charges of disorderly conduct and interfering with a police officer.

A group of about 40 to 50 demonstrators assembled just before 6 p.m. at Colonel Summers Park, located at SE Belmont Street and 20th Avenue to rally and march to protest police brutality.

Protesters did not share with police or the media the route they planned to take.

According to local fliers, the march was “in solidarity with Occupy Oakland and against corruption."

Several protesters said they were not only protesting against police brutality in Oakland, Calif. but also in Portland.

There was a light police presence at 6:30 p.m. At least three police officers were observed to be following the group. But less than an hour later police in riot gear were observed following a group of protesters who had apparently split off from the group.

Police told marchers over a loudspeaker to get out of the streets or they would "be subject to use of force."

At one point protesters pulled trash cans out into the middle of the street at Belmont and 25th but other protesters chastised them, saying that was not what the movement was about. The trash cans were then put back.

Some damage was observed along the path of the march, including a glass door at Genoa Restaurant with holes in it and a car sprayed with paint.

Some protesters said the damage stemmed from a separate group.

"People rammed their flag through (Genoa's) window," said protester Chase Wilson. "We were marching in the street and when we saw this we all rallied up and tried to find the person who did it."

A car's front windshield was also smashed up.

Police said no one was arrested for any acts of vandalism but they are still investigating the incidents.

Police said earlier in the day they were concerned about the march because the tone and information about the event was more hostile than previous rallies and marches.

Police said protesters did not have a permit.

Before the march, KATU News spoke with Occupy Portland member David Osborn, who said concerns by Portland police were unfounded.

“What we have is the Portland Police Bureau trying to whip up a hysteria,” said Osborn.
